Insira anúncios em streams em direto

Esta página mostra como inserir anúncios numa transmissão em direto através da API Video Stitcher e do curl, do PowerShell ou das bibliotecas de cliente.

Antes de começar

Antes de chamar a API Video Stitcher, conclua os seguintes passos:

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

Install the Google Cloud CLI.

Se estiver a usar um fornecedor de identidade (IdP) externo, tem primeiro de iniciar sessão na CLI gcloud com a sua identidade federada.

Para inicializar a CLI gcloud, execute o seguinte comando:

gcloud init

Create or select a Google Cloud project.

Roles required to select or create a project

Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

Create a Google Cloud project:
```
gcloud projects create PROJECT_ID
```
Replace PROJECT_ID with a name for the Google Cloud project you are creating.
Select the Google Cloud project that you created:
```
gcloud config set project PROJECT_ID
```
Replace PROJECT_ID with your Google Cloud project name.

Verify that billing is enabled for your Google Cloud project.

Enable the Video Stitcher API:

Roles required to enable APIs

To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

gcloud services enable videostitcher.googleapis.com

If you're using a local shell, then create local authentication credentials for your user account:

gcloud auth application-default login

You don't need to do this if you're using Cloud Shell.

If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/videostitcher.admin

gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

Replace the following:

PROJECT_ID: Your project ID.
USER_IDENTIFIER: The identifier for your user account. For example, myemail@example.com.
ROLE: The IAM role that you grant to your user account.

PROJECT_ID: Your project ID.
USER_IDENTIFIER: The identifier for your user account. For example, myemail@example.com.
ROLE: The IAM role that you grant to your user account.

Este início rápido requer um ficheiro de manifesto MPEG-DASH ou HTTP Live Streaming (HLS). Pode criar uma seguindo um dos inícios rápidos da API Live Stream até à secção Reproduzir a stream em direto gerada.
Em alternativa, pode usar uma rede de fornecimento de conteúdo (RFC) com este início rápido. Se não configurou uma RFC, siga os passos no guia de início rápido da RFC de multimédia com as seguintes modificações:
1. Carregue ficheiros de manifesto MPEG-DASH ou HLS e segmentos de multimédia para o contentor do Cloud Storage.
2. Não tem de tornar o seu contentor do Cloud Storage publicamente legível.
3. Pode usar URLs assinados ou não assinados.

Crie uma chave da RFC

A API Video Stitcher pode obter vídeos de uma rede de fornecimento de conteúdo (RFC). Se o recurso de vídeo estiver protegido pela assinatura de URL, tem de ser registada uma chave de RFC junto da API Video Stitcher.

Para registar a chave de CDN, use o método projects.locations.cdnKeys.create.

REST (Media CDN)

Antes de usar qualquer um dos dados do pedido, faça as seguintes substituições:

PROJECT_NUMBER: o número do seu Google Cloud projeto; este encontra-se no campo Número do projeto na página Definições do IAM
LOCATION: a localização na qual criar a chave de RFC; use uma das regiões suportadas

Verifique o resultado

Para verificar se a chave de RFC foi criada, use o método projects.locations.operations.get. Se a resposta contiver "done: false", repita o comando até que a resposta contenha "done: true".

Antes de usar qualquer um dos dados do pedido, faça as seguintes substituições:

PROJECT_NUMBER: o número do seu Google Cloud projeto; este encontra-se no campo Número do projeto na página Definições do IAM
LOCATION: a localização dos dados; use uma das regiões suportadas

Depois de receber a resposta, pode ver a stream em direto com anúncios incorporados consultando o URI no campo playUri do objeto de resposta.

A API Video Stitcher gera um ID de sessão exclusivo para cada pedido. Uma sessão expira se o playUri não for pedido nos últimos 5 minutos.

Veja a stream em direto com anúncios integrados

Reproduza a stream em direto com anúncios incorporados através do URI do campo playUri do objeto de resposta. Para ver esta stream em direto no Shaka Player, conclua os seguintes passos:

Navegue para o Shaka Player, um leitor de multimédia online.
Clique em Conteúdo personalizado na barra de navegação superior.
Clique no botão +.
Cole o valor do campo playUri (PLAY_URI) na caixa URL do manifesto.
Introduza um nome na caixa Nome.
Clique em Guardar.
Clique em Jogar.

Insira pausas para anúncios

A API Video Stitcher insere anúncios obtidos a partir da etiqueta do anúncio para cada pausa para anúncios. As pausas para anúncios são indicadas no manifesto através de marcadores de anúncios. Os marcadores de anúncios são inseridos pelos codificadores de streams em direto. Para mais informações sobre os marcadores de anúncios HLS e DASH suportados, consulte a documentação de marcadores de anúncios.

Se usou a API Live Stream para criar a stream em direto, pode usar eventos do canal para inserir pausas para anúncios.

Confirme se um anúncio foi unido

Um anúncio tem de ser codificado antes de poder ser integrado numa sessão em direto. Se vir um vídeo de slate em vez de um anúncio, aguarde pela codificação do anúncio e insira outra pausa para anúncios.

Limpar

Para evitar incorrer em custos na sua Google Cloud conta pelos recursos usados nesta página, elimine o Google Cloud projeto com os recursos.
